    TLDR Some patients developed skin inflammation after obesity surgery, and a medication called dapsone helped treat it.
    In a 42-year-old study of 105 patients who had jejuno-ileal bypass surgery for morbid obesity, 7 (approximately 7%) developed inflammatory skin lesions, which were sometimes accompanied by joint pain, tenosynovitis, muscle pain, and fever. These lesions were characterized by erythema with central vesicles or pustules, and neutrophil accumulation was a common feature. Circulating immune complexes were found in patients with active and remitted lesions, as well as in those without lesions. Dapsone was effective in treating these symptoms when other antibiotics failed. The study suggested that these complications were episodic and mostly self-limiting, with no definitive evidence for the role of circulating immune complexes. The document also explored the potential factors contributing to the development of these complications and noted that while the exact cause was unclear, certain treatments were beneficial.

      Scalp biopsies are crucial for diagnosing hair loss conditions like Diffuse Unpatterned Alopecia (DUPA) and retrograde hair loss, as treatments like finasteride and dutasteride may not be effective if other conditions are present. Combining PPAR-GAMMA agonists with retinoids could improve treatments for conditions like Lichen Planopilaris.

      The conversation discusses potential hair loss treatments focusing on stimulating IGF-1 at the follicle level using growth-factor cocktails and engineered peptides, such as Acetyl Tetrapeptide-3, Copper Tripeptide-1, Oligopeptide-20, Thymosin-β4, and Palmitoyl Tetrapeptide-7. It suggests that device-assisted delivery methods like microneedling may enhance effectiveness.

      The user experienced no improvement in hair loss after using a dermatologist's minoxidil 10% and finasteride 0.1% solution, clotrimazole, daily dermarolling, and multivitamins. They plan to switch to oral finasteride and reduce dermarolling to once a week.
